TIPPING MACHINE.

Application led May 3,

To all whom t may concern;A

Be it known that I, JOHN I-I. RoYALL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements in TippingMachines, of which the following is a specification.

This invention relates to tipping machines and particularly to machinesfor placing tips on shoe laces. One of the principal objects of thedevice is to provide tip clinch ing jaws which shall move directlytoward and from each other and which always remain in parallel relationwith each other.

Another Objectis to form the jaws with teeth which shall interlock so asto ensure a perfect operation.

Another object is to produce a device of this nature which shall besimple of construction, cheap to manufacture, and highly efficient forthe purpose for which'it is devised.

With these and other objects in view as will be more apparenthereinafter, the invention consists in certain novel construction andcombination and arrangement of parts, the essential features of whichare hereinafter fully described, are particularly pointed out in theappended claims, and are illustrated in the accompanying drawing, inwhich Figure 1-is a side elevation of my improved tipping machine.

Figure Q-is a front end elevation of the same.

Figure S-is a detail top plan view of one of the dies or jaws.

Figure 1 -is an end view of the device in operative position.

Like characters of reference refer to like parts in all the views.

Referring to the drawing in detail, 10 and 11 represent handles, each ofwhich terminates in a respective pair of lingers 12 and 13. Between thelingers 12 of the handle 10 is pivoted a jaw 14, the pivot being shownat 15. Similarly a jaw 16 is pivoted to the fingers 13 at 17. Each ofthe jaws 14 and 16 is bifurcated at its rear end to straddle re- 1924.Serial* No. 710,917.

spective pins 18 and 19 carried by the fingers 13 and 12, respectively.

'Ihe jaws 16 and 111 are provided with a plurality of teeth 20 whichextend transversely of the jaws and which are formed with V-shapednotches 21, terminating in curvilinear portions 22. The teeth of thejaws are staggered so as to interlock when the jaws are broughttogether.

At the back of the jaws are ,two teeth 30 of half the height of teeth 20and considerably broader.4 These two teeth meet and are provided with ataper way 31 as shown in Figure 3.

In use, the lace with the tip is placed between tlle aws, and then thehandles 1() and 11 are squeezed together whereby the teeth 20 arebrought into interlocked relation and pressed home until they assume theposition shown in Figure 4l at which time they have completely closedthe tip on the lace and have crimped it at the intersection of each pairof teeth, the back teeth 30 making a tapered end on the tip.

IVhile I have described what I deem to be the most desirable embodimentof my invention, I do not limit myself to the specific details ofconstruction or material, nor to anything less than the whole of myinvention as defined in the appended claims.

IVhat I claim is 1. A tipping device comprising a pair of jaws, teetharranged thereon, the teeth of one jaw being staggered with relation tothe teeth of the other jaw, a short broad tooth on each jaw adjacent tothe innermost first named tooth, said short broad teeth provided withtapered ways in their facing surfaces for tapering the end of a tip.

2. A tipping device comprising a pair of jaws, teeth arranged thereonand having V- shaped notches, the notches in the teeth of one jawaligning with the notches in the teeth of the other jaw, the teeth ofone jaw being staggered with relation to the teeth of the other jaw, ashort broad tooth on each jaw adjacent to the innermost first namedteeth, said short broad teeth provided with tapered ways in their facingsurfaces for tapering the end of a tip, and means for moving said jawst0 bring the teeth into interlocked relationship.

3. A tipping device comprising a pair of jaws, teeth arranged thereonand having V- shaped notches, the notches in the teeth of one jawaligning with the notches in the teeth of the other jaw, the teeth ofone jaw being staggered with relation to the teeth of the other jaw, ashort broad 'tooth on each jaw adjacent to the innermost first named 10tel-locked relationship and parallel one to l5 the other.

In testimony whereof I ailix my signature.

JOHN H. ROYALL,
